Rationale: Catheter-related thrombosis is a serious complication of lung transplantation under venovenous extracorporeal membrane oxygenation (ECMO). Although ECMO-related thrombosis is not uncommon, there are few reports of giant hollow catheter thrombosis in lung transplantation under venovenous ECMO (ECMO). Blood loss and transfusion of coagulation factors may promote ECMO-related thrombosis. Hollow catheter thrombus was not detected on ultrasonography performed after initiation of ECMO. Therefore, it is essential to identify, manage, and reduce or avoid such thrombosis. Patient concerns: We report a rare case of a 43-year-old man with advanced silicosis who developed a massive hollow catheter thrombus during lung transplantation. Anticoagulant therapy did not affect the size of the thrombus. Diagnosis: Giant hollow catheter thrombosis was diagnosed by ultrasonography. Thrombosis from the right external iliac vein to the inferior vena cava was found in the shape of the ECMO pipe. Interventions: Heparin was prescribed as an anticoagulant. Outcomes: Anticoagulant therapy did not affect the size of the thrombus during 2 weeks. The patient developed an infection and died of multiple organ failure. Conclusion: It is uncommon for massive hollow thrombus to occur during venovenous-ECMO-assisted lung transplantation. Fibrinogen and prothrombin complexes promote the formation of thrombus, and the measurement of the wall thickness of ECMO catheter may help to detect such thrombus.
